Quantum advantage bounds for a multipartite Gaussian battery
F. Cavaliere, D. Ferraro, M. Carrega +2
We demonstrate the possibility of a genuine quantum advantage in the efficiency of quantum batteries by analyzing a model that enables a consistent comparison between quantum and c…
Enhanced shot noise in graphene quantum point contacts with electrostatic reconstruction
M. Garg, O. Maillet, N. L. Samuelson +13
Shot noise measurements in quantum point contacts are a powerful tool to investigate charge transport in the integer and fractional quantum Hall regime, in particular to unveil the…
Superconducting Quantum Interference Devices based on InSb nanoflag Josephson junctions
Andrea Chieppa, Gaurav Shukla, Simone Traverso +10
Planar Josephson junctions (JJs) based on InSb nanoflags have recently emerged as an intriguing platform in superconducting electronics. This letter presents the fabrication and in…
Hybrid interacting quantum Hall thermal machine
S. Finocchiaro, D. Ferraro, M. Sassetti +1
We investigate a hybrid thermal machine based on a single closed quantum Hall edge channel forming a quantum dot. It is tunneling coupled with two quantum Hall states at in…
